SPECIFICATION forming part of Letters Patent No. 744,872, dated November 24;, 1903.

Application filed February 17, 1903. Serial No. 143,790. (No model.)

described which has various advantages asto convenience in use, simplicity and cheapness of construction, general efficiency, well adapted to carry heavy loads, while at the same time the difierent portions of the car are easily accessible for inspection and repairs.

To make the matter more clear, I will now refer to the two annexed sheets of drawings, which form part of this specification, and in which like figures refer to like parts.

Figure 1 is a side elevation of my improved car, in which the nearest of the Wheels and the axle-journal therefor at the right-hand side of the figure are removed for the purpose of showing clearly the parts which would otherwise be hidden. Fig. 2 is a plan of my improved car. Fig. 3is atransverse sectional elevation on the line A A of Fig. 1 looking in the direction of the arrows. Fig. eis an end elevation of the front or closed end of my improved car, and Fig. '5 is an end elevation of the back or door end thereof.

Referring now to the various characters of reference upon the drawings, 1 is the bottom or floor plate of the car.

2 represents the side plates, flaring at the top, as shown.

3 is a plate forming the front or closed end of my improved car, and 4 is a similar plate forming the body of the door at the other end of said car.

5 is a stiffener, shown 'as a bent angle secured to the upper portions of the flaring sides, and,as shown in Figs. 2 and 3,this bentangle stiffener 5 is continuous across the bottom of the car and serves to greatly strengthen it, as may be readily understood.

6 represents bent-anglestiffeners orbraces secured to the lower external corners of the car-body and to the upper portion of the liaring sides, as shown.

It will be noted that the construction and arrangement of the two forms of stiffeners, shown as bent angles, is such thatin connection with the vertical and flaring sides of the car they form lateral trusses of approximately triangular form, which thus makes a very stiff strnctu re with respect to the stresses to which it is naturally subjected, and these are particular and important features of my invention.

7 represents angles extendinginwardly and down the ends of the side plates of the car for securing the front end plate 3 to the car sides, and 8 is an angle extending across the bottom or floor plate 1 for securing the front end plate to the floor-plate.

9 represents fiat bars riveted t0 the car sides at the door end for giving stiffness thereto. These fiat bars 9 are bent to fit the outside of the car sides, and also project vertically above the same for the purpose of providing a support for the shaft 10,0n which the doorplate 4 is revolubly mounted by means of the hinges 11, secured thereto.

12 represents axles of square cross-section provided at their ends With cylindrical journals for the wheels 13, which may be of any approved pattern. As shown in Figs. 1 and 3, the axles 12 are secured directly to the bottom plate by means of the straps 14 for the purpose of keeping the car-body as low as possible without using very small wheels. This feature of my construction is important, as it provides a car of large capacity in a small height, which is a valuable consideration in minework.

To further stiffen the ends of my improved car and to prevent any buckling thereof, I rivet thereto heavy angles 15, which extend longitudinally of the lower edges of the car sides and thence curve inwardly, as shown in Fig. 2, to form a rigid bumper-support.

16 represents bumpers formed of bent plates. 17 represents filler-plates or end sills for said bumpers, extending the whole width of the bumper end. 18 represents straps which in IOU connection with said end-sill plates 17 and the floor-plate 1 serve as bearings for the coupling-pin 19. The wings of the straps 18 extend transversely under the floor-plate and also serve as fillers'for the bumper construction.

21 is a chain fastened to the car-floor plate, provided at its loose extremity with a ring 22, which passes through an opening 23 in the door-plate, and in connection with a latch 24, which oscillates about a pivot 25, serves to hold the door in its closed position. When it is desired to discharge the contents of the car, said latch 24 is made to revolve toward the left, allowing the ring 22 to slip through opening 23, thus releasing the end gate or door.

26 represents chains or flexible connections which serve to secure the coupling-pins 19 to the car and prevent the loss of said pins.

20 represents angles for securing the sides to'the floor-plate.

The end bumpers 16 are. each composed of a rectangular plate bent into form, as shown, the outer or contact ends being substantially flat, the upper portion of which is braced by the inclined part, the projecting ends of the plate being parallel and separated a suitable distance apart for attaching to the end extensions of the car-body, as shown. The longitudinal section of each of these bumpers has a substantially triangular outline with rounded corners and parallel projections spaced apart and provided with holes for attaching the bumpers to the extended portions of the floor-plate and its reinforcing end sillplate.

Although I have shown my improvements in considerable detail, I do not limit myself to the exact and definite particulars of the construction, arrangement, or sections shown and described, but may use such substitutions, modifications, or equivalents thereof as are embraced within the scope of my invention and as pointed out in the claims.

Having thus given a general description of.

my invention, what I claim, and desire to se cure by Letters Patent, is-

1. In a mine-car, a floor-plate, sides secured thereto, said floor-plate being longer than said sides thus forming extensions at both ends of said car, bumpers mounted on said extensions, heavy angle members secured to the lower corners of the car-body for bracing said extensions, a front end and an end gate suitably connected to the sides aforesaid.

2. In a mine-car, a floor-plate, sides secured thereto, said floor-plate being longer than said sides thus forming extensions at both ends of said car, heavy angle members projecting from the lower corners of the car-body secured to and forming braces for said extensions, and bumpers formed of bent plates mounted on the extensions aforesaid.

3. In a mine-car, a floor-plate, sides secured thereto, said floorplate being longer than said sides, forming segmental extensions at both ends of said car, heavy angle members secured to the lower corners of said car and projecting from the car-body under and alongside of said extensions, said angle members being curved inwardly forming the circular outline of said extensions, and bumpers formed of bent plates mounted on the extensions aforesaid.
